Columbia County, FL Home Business: Signage Rules (2026)

Section 4.2.31(3) is the sign clause inside the county's home occupation standards. It says there shall be no change in the outside appearance of the building or premises, or other visible evidence of the home occupation, other than one sign, capped at 16 square feet, that must be non-illuminated and mounted flat against the wall of the principal building, no more than two feet from the main entrance to the residence. That single flat wall sign is the only exterior marketing a home-based business is allowed under these regulations; a freestanding yard sign, an illuminated sign, or a second sign would violate the section even if each one individually would fit under the 16-square-foot cap.

The 16-square-foot, wall-mounted standard is smaller and more restrictive than the county's general occupational sign exemption elsewhere in the Land Development Regulations, which allows a freestanding occupational sign up to 16 square feet without a permit for other properties; a home occupation instead must follow the tighter wall-mounted placement rule in Section 4.2.31(3) because that section governs specifically. Because the sign standard sits inside the home occupation approval, the land development regulation administrator reviews it along with the rest of the Section 4.2.31 conditions, and installing a noncompliant sign can jeopardize the underlying home occupation approval, not just draw a sign citation.
